Description

Technical Field

[0001] This application relates to the field of circular knitting machines, and in particular to a circular knitting machine with yarn supply adjustment function. Background Technology

[0002] Circular knitting machines are high-efficiency equipment for producing knitted fabrics, widely used in clothing, home textiles, and industrial textiles. Their yarn feeding system is responsible for the stable delivery of yarn, ensuring knitting quality. When the circular knitting machine is working, the yarn needs to travel a specific path from the yarn bobbin to the knitting area. However, existing circular knitting machines have fixed yarn feeding system positions. For different yarn types, yarn bobbin sizes, and knitting speeds, it is difficult to maintain uniform yarn tension during the feeding process. The fixed position of the yarn feeding system cannot adequately adapt to the use of various yarn materials, requiring companies to configure multiple yarn feeding systems of different sizes for different yarns, increasing costs. Furthermore, multiple yarn feeding systems mean the need to stock more types of spare parts, increasing equipment maintenance costs. Utility Model Content

[0039] Reference Figures 1-6A circular knitting machine with yarn supply adjustment function includes a machine body 1, a top seat 11 on the machine body 1, and several support seats 2 arranged at intervals along the circumference of the top seat 11. One end of the support seat 2 extends to the outer periphery of the top seat 11. The support seat 2 has a sliding groove 21, and a first push rod component 3 is arranged in the sliding groove 21. The piston end of the first push rod component 3 is connected to the sliding seat 31 and fixed to the support 4. The extension and retraction of the piston end in the first push rod component 3 can drive the sliding seat 31 to move. A receiving part 41 is movably arranged on the support 4. A bracket 42 is arranged on both sides of the receiving part 41. Several yarn feeders 421 are installed on the bracket 42 at intervals. The arrangement of several support seats 2 can enable several yarn feeders 421 to be installed on the machine, thereby improving the yarn supply efficiency. Furthermore, the support seats 2 symmetrically arrange the yarn feeders 421 around the center of the circular knitting machine, avoiding the intersection of yarn transport paths, reducing space occupation, and adapting to the needs of circular knitting process.

[0040] With the cooperation of the first push rod component 3, the slide block 31 moves relative to the slide groove 21 along its length, causing the position of the yarn feeder 421 to change synchronously. The receiving part 41 can drive the yarn feeder 421 to move relative to the support 4 along its length. With the cooperation of the first push rod component 3, the lateral position of the yarn feeder 421 can be changed. With the movement of the receiving part 41 on the support 4, the vertical position of the yarn feeder 421 can be changed. Thus, the position of the yarn feeder 421 can be flexibly adjusted according to different yarn requirements to adapt to the weaving needs of complex patterns and yarns.

[0041] An extension plate 43 is provided on the top of the support 4, and a second push rod component 5 is provided on the extension plate 43. The piston section of the second push rod component 5 passes through the extension plate 43 and is equipped with a limiting rod 51. Through the cooperation of the second push rod component 5, the limiting rod 51 is brought closer to or away from the top seat 11. When the yarn enters the machine body 1 for weaving with the cooperation of the yarn feeder 421, the yarn is located below the limiting rod 51. Through the cooperation of the second push rod component 5, the limiting rod 51 can be made to abut against the yarn and apply pressure to the yarn, thereby adjusting the tension of the yarn. When the limiting rod 51 abuts against the yarn, the amplitude of the yarn feeder 421 is reduced, and the stability of the yarn tension is improved.

[0042] Based on the above structure, the yarns on the yarn bobbins are respectively installed on the yarn feeders 421 located on the bracket 42, and enter the machine body 1 with the cooperation of the yarn feeders 421. According to the condition of the yarn, the first push rod component 3 drives the slide block 31 to move, so that the slide block 31 drives the support 4 to change position, thereby causing the yarn feeder 421 to drive the yarn to move laterally along the length direction of the slide groove 21, thus completing the stretching of the yarn. Furthermore, the yarn feeder 421 is installed on the bracket 42 connected to the receiving part 41. By moving the receiving part 41 on the support 4, the vertical position of the yarn is changed, thereby completing the stretching of the yarn. The re-stretching of the yarn, through the cooperation of the support 4 and the receiving part 41, enables the yarn feeder 421 to move the yarn to different positions, thereby making appropriate adjustments according to the different types of yarn. When the yarn enters the machine body 1, it is below the limiting rod 51. According to the required tension of the yarn, the second push rod part 5 can drive the limiting rod 51 to move, so that the limiting rod 51 applies pressure to the yarn frame, thereby adjusting the yarn tension. This enables adjustments according to the type of yarn, solving the problem that the existing yarn feeding device has a fixed position and cannot be adjusted, resulting in an inability to flexibly adjust according to the yarn condition.

[0043] The first push rod component 3 and the second push rod component 5 mentioned above are both adopted as any one of the pneumatic push rod, electric push rod and hydraulic push rod in the prior art.

[0044] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 A storage component 6 is provided on the side of the receiving part 41 away from the extension plate 43. The storage component 6 is used to place the yarn bobbin, thereby avoiding the need for an additional support 42 for yarn bobbin spinning. The storage component 6 includes a placement seat 61 and a movable rod 62. One end of the placement seat 61 is connected to the receiving part 41. A support rod 611 is provided on the side of the placement seat 61 away from the receiving part 41. The support rod 611 is perpendicular to the placement seat 61. This vertical arrangement allows the support rod 611 to support the yarn bobbin. The end is limited, and the placement seat 61 has a through hole 612. The movable rod 62 is installed on the through hole 612, so that a receiving area for placing the yarn bobbin is formed between the movable rod 62 and the support rod 611. When the yarn bobbin is placed between the movable rod 62 and the support rod 611, the yarn bobbin is placed, which improves the utilization rate of the space of the large circular knitting machine. In addition, the movable rod 62 and the support rod 611 are parallel, providing multi-point contact support when the yarn bobbin rotates at high speed, reducing radial runout and optimizing dynamic stability.

[0045] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 5The slide groove 21 has hollowed-out portions 211 on both sides, and a shaft 212 is provided in the hollowed-out portion 211. Several shafts 212 are provided and distributed at intervals along the length of the hollowed-out portion 211. Roller components 2121 are sleeved on the shafts 212. When the slide block 31 is located in the slide groove 21, the outer periphery of the roller component 2121 abuts against the side wall of the slide block 31. The roller component 2121 converts the sliding friction between the slide block 31 and the slide groove 21 into rolling friction, which significantly reduces the energy consumption and wear when the slide block 31 moves. In addition, the multiple roller components 2121 are distributed along the length of the slide groove 21 to form a continuous rolling support surface, preventing the slide block 31 from tilting or getting stuck, and ensuring linear motion accuracy.

[0046] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 Several through holes 612 are provided and distributed at intervals along the length of the placement seat 61. The movable rod 62 is installed on any of the through holes 612. By installing the movable rod 62 on different through holes 612, the range of the accommodating area can be expanded or reduced. By selecting different through holes 612 to install the movable rod 62, the accommodating area can be quickly expanded or reduced to adapt to continuous size changes from small yarn bobbins to large yarn bobbins, thereby improving the flexibility when installing yarn bobbins.

[0047] The placement seat 61 is provided with a blocking part 613. The blocking part 613 forms a first accommodating area and a second accommodating area in the accommodating area. When two sets of yarn bobbins are placed side by side on the support rod 611, the blocking part 613 physically isolates the adjacent yarn bobbins, preventing the yarn from tangling during unwinding and optimizing the weight balance. This allows for the simultaneous placement of two different specifications or colors of yarn bobbins by partitioning, thus supporting the needs of complex weaving processes.

[0048] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 The support 4 has several limiting holes 44 spaced apart along its length. The arrangement of several limiting holes 44 improves the flexibility of selection. The receiving part 41 has a mounting hole 411 with the same diameter as the limiting holes 44. When the mounting hole 411 is aligned with one of the limiting holes 44, a pin is installed between the mounting hole 411 and the limiting holes 44. The pin provides a purely mechanical lock. The same hole diameter facilitates the passage of the pin. By selecting limiting holes 44 of different heights for alignment, the installation position of the receiving part 41 can be changed, realizing multi-level adjustment of the yarn bobbin conveying angle or height. This fixes the receiving part 41 on the support 4, preventing the receiving part 41 from causing the yarn bobbin to shake during yarn feeding, thus avoiding deviation and ensuring the connection strength between the receiving part 41 and the support 4 under high load conditions.

[0049] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The slide groove 21 is provided with a guide rail 213, and the bottom of the slide block 31 is provided with a groove 311. When the slide block 31 is located in the slide groove 21, the guide rail 213 is embedded in the groove 311. The engagement of the guide rail and the groove 311 constrains the movement direction of the slide block 31, avoids lateral displacement, and ensures the consistency of the yarn bobbin conveying path.

[0050] In one embodiment, reference is made to Figures 1-3 Both the limiting rod 51 and the bracket 42 adopt an arc-shaped structure, and the arc centers of the limiting rod 51 and the bracket 42 are the same. The arc-shaped structure guides the yarn along a natural curve path, reducing the sudden change in local tension caused by sharp bends and reducing the probability of yarn breakage.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
